In the kitchen I use Pi3/Allo boss...Lepai 2020A+.....Pair of Tannoy Mercury 2.5 and thinking about adding a M+K K9 that I've got kicking about just to beef up the bottom end a little (not that it needs it).
Think I called the Lepai 'Crappy' in a earlier post, Couldn't have been more wrong It's amazing for the money and perfect size for a kitchen, Plenty of hacks available for this little amp but I guess you can kiss the 'bang for buck' factor goodbye then, Later models and copies don't seem to have very kind reviews though.
Bedroom: RPi 3 B+ / HifiBerry DAC+ Pro and Chromecast Audio to Creek 5350se integrated amp ($1500USD in 2002!). Mirage M290i speakers (Canada).
Sadly Creek used a crappy (cheap) input selector switch from ALPS, which started failing after ~5 years. Since then have lived with the occasional channel drop-outs and static-y noise. If I were doing it again I'd avoid Creek (and I did: bought a Micromega M-100 all-in-one amp for main hifi system).
Hello I have been using Hypex nCore400 Monos for some time and am extremely satisfied. The expensive BAT Pre- and Power-Amp did not show the quality, so I switched to nCore. Hypex nCore are for me absolute master amps!
